Abstract

Polymerizable liquid-crystalline siloxanes of a defined composition which are distinguished by low viscosity and pronounced thermochromic properties. The liquid-crystalline siloxanes of the present invention are used for the production of membranes in the optical display of electromagnetic field, opto-electronics, information storage and in particular in the production of optical filters and reflectors.
